Give your Mustang a valved exhaust and a polished quad-tip finish

The sound hardware and rear finish together
The H-pipe, 3" mid-pipes and rear pipes are supplied with the Shotgun valved muffler sections. Quad polished stainless tips complete the visible upgrade, bringing the rear system and finish together in one package.
Match the bumper and front connection
This system requires a Mustang that already has quad tips or is using a quad-tip bumper. Its 2-1/4" inlet makes the factory-style front connection, while the main exhaust pipework is 3".
